Answer:
Intercept, b = 38
Explanation:
Given the following data;
Point on x-axis = -4
Point on y-axis = 2
Slope, a = 9
To find the y-intercept (b);
Mathematically, the equation of a straight line is given by the formula;
y = ax + b.
Where;
a is the slope.
x and y are the points on the line.
b is the intercept.
Substituting into the formula, we have;
2 = 9(-4) + b
2 = -36 + b
b = 36 + 2
Intercept, b = 38
