Answer:

y = 3/4x - 3

Explanation:

Slope = - 3/4, point (0, -3)

y - -3 = - 3/4 (x - 0)

y + 3 = - 3/4x

y = 3/4x - 3

(The slope is go up three from point ( 0,-3 ) and 4 to the left to (-4,0). The y-intercept is -3)

Answer:

y = -3/4x -3

Explanation:

The equation for a line in "intercept form" is ...

x/a +y/b = 1

where 'a' is the x-intercept and 'b' is the y-intercept. Here, the x-intercept is -4, and the y-intercept is -3. This means the equation can be written as ...

x/(-4) +y/(-3) = 1

Solving for y, we get ...

y/(-3) = x/4 +1 . . . . . . . . . . . add x/4

y = -3/4x -3 . . . . . . . . . . . . multiply by -3

_____

Alternate solution

The slope of the line (m) is the ratio of "rise" to "run". Here, the line drops 3 squares for a run of 4 squares to the right, so ...

m = rise/run = -3/4

The line crosses the y-axis at y=-3, so that is the value of the y-intercept.

The slope-intercept form of the equation for a line is ...

y = mx +b . . . . . . for slope m and y-intercept b

This line is ...

y = -3/4x -3
