Answer:
please see detailed description below
Explanation:
equation on straight line is given by y = mx + c (where m is gradient-slope, c is y-axis intercept).
our slope, m, is found by picking two sets of coordinates.
let's pick the two dotted points on the diagram.
(-2 ,0) and (0, -3)
slope = (change in y values) / (change in x values)
= (-3 - 0) / (0 - -2)
= -3 /(0 + 2)
= -3 /2
the graph crosses the y-axis at y = -3.
the equation of the line is y = (-3/2)x - 3
the slope is -3/2
