Question

Write the slope-intercept equation for the line with slope -3/7 and y-intercept (0, -5) and graph the line?

Answer 1

Given m = -3/7

y intercept = -5

Equation of the line slope intercept form is y = mx+b

y = (-3/7)x+(-5)

y = -(3/7)x-5

Answer 2

• Slope - intercept - form of a line equation is y = mx + b, where m is slope, and b is y - intercept

Slope (m ) = - 3/7.

y - intercept (b ) = -  5.

Now the line equation is y = (- 3/7)x - 5.

• y - intercept is - 5, so the line crosses the y - axis at (0, - 5).

  Using slope find the next point.

  Slope = rise/run = - 3/7.

  Start at point (0, - 5), move 3 units down and 7 units right, then plot the point (7, - 8).

  Draw a line through these points.
