What equation is perpendicular to Y 3x2?

2 Answers By Expert Tutors So the line perpendicular to y = 3x – 2 has a slope of -1/3. That’s the answer. If they want you to give the answer in the y= mx + b format (slope-intercept) then multiply it out and combine like terms.

How do you find the Y-intercept when given two points?

1. Calculate the slope from 2 points. For Example, Two points are (3, 5) and (6, 11)
2. Substitute the slope(m) in the slope-intercept form of the equation.
3. Substitute either point into the equation. You can use either (3,5) or(6,11).
4. Solve for b, which is the y-intercept of the line.
5. Substitute b, into the equation.

What is an equation that is perpendicular to Y =- 1 2x 3?

The y-intercept is y=2 .

How do you find the y-intercept without graphing?

To find the x-intercept of a given linear equation, plug in 0 for ‘y’ and solve for ‘x’. To find the y-intercept, plug 0 in for ‘x’ and solve for ‘y’.

What is the y-intercept in y MX B?

In the equation of a straight line (when the equation is written as “y = mx + b”), the slope is the number “m” that is multiplied on the x, and “b” is the y-intercept (that is, the point where the line crosses the vertical y-axis).

What does y-intercept of 1 mean?

Solution. The y-intercept of a line is where it crosses the y-axis. In this case, the line crosses at around y = -1. The value of x, by definition is 0 and the x-axis represents the number of cups of coffee a person drank last week.

What is the y-intercept of Y 1 2x 5?

Using the slope-intercept form, the y-intercept is −5 .

What is the slope and the y-intercept in the equation y =- 2x?

Therefore: The slope is: m=2. The y -intercept is: b=0 or (0,0)

What is the slope of y =- 2 5x 6?

Using the slope-intercept form, the slope is 25 . The equation of a perpendicular line to y=2×5−6 y = 2 x 5 – 6 must have a slope that is the negative reciprocal of the original slope.

The slope is 3 .

What is the equation of the line that goes through 2 3 and is perpendicular to Y =- 3x 1?

Equation of given line 2y=3x-1 needs to be rearranged to find slope y=3/2x-1/2; coefficient of x is 3/2 so slope is m=3/2. Slope of the perpendicular line is the negative reciprocal of the given equations’ slope. So new slope is -2/3.

What is the slope of the line defined by the equation y − 3x − 4?

y=mx+b. Using the slope-intercept form, the slope is −3 .

How do you find the Y intercept of a perpendicular line?

Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6. Thus, the equation of the line is y = ½x + 6. Rearranged, it is –x/2 + y = 6.

How do you write the equation of a line that is perpendicular to a line?

The given equation is in standard form, so it must be converted to slope-intercept form: y = mx + b to discover the slope is –2/3. To be perpendicular the new slope must be 3/2 (opposite reciprocal of the old slope).

How would you write the equation with a slope of 2/3 and a Y intercept of 3?

In other words you need to have X=0, so your point is X=0 and Y=-3. Second, you have the value of the slope which is 2/3. m = 2/3 and b = -3, where m is the slope and b is the y-intercept. We will use the slope-intercept form: y = mx + b.
