Question

Find the slope intercept form. Y=MX+B

Answer 1

y = -7/2x -7/4is the answer

Answer 2

y = -4/5x -8/5

Explanation:

You want the slope-intercept equation of the line shown in the graph.

Points

It is easier to write the equation if we know some grid points that the line crosses. Here, we believe the best choice of such points to be ...

(-2, 0) and (3, -4)

Slope

The slope of the line can be found from ...

`m=(y_2-y_1)/(x_2-x_1)=(-4-0)/(3-(-2))=-(4)/(5)`

Equation

Using the point-slope form of the equation for a line, we can solve for the slope-intercept form.

y -k = m(x -h) . . . . . . . line with slope m through point (h, k)

y -0 = -4/5(x +2) . . . . . . . line with slope -4/5 through point (-2, 0)

y = -4/5x -8/5 . . . . the desired equation
