First, find the slope using the points (-56, 66) and (-42, 58).
Slope formula: y2-y1/x2-x1
= 58-66/-42-(-56)
= -8/14
= -4/7
Use slope-intercept form to solve for the y-intercept.
y = -4/7x + b
66 = -4/7(-56) + b
66 = 32 + b
66 - 32 = 32 - 32 + b
34 = b
Therefore, the y-intercept of the line is (0, 34).
Best of Luck!
