Answer:
y-intercept = 31
Explanation:
The equation of a straight line in slope-intercept form is y = mx + b, where m is the slope, and b is the y-intercept.
As we know that 11 is the slope, our equation now becomes y = 11x + b.
To find b, you take the given point, and plug the numbers in for x and y in the equation. Now x = 7, and y = 108.
Your equation is now 108 = 11(7) + b and you can solve for b, your y-intercept.
108 = 11(7) + b
108 = 77 + b
31 = b
Therefore, your y-intercept is 31.
