A line that passes through the point (x,y), with a y-intercept of b and a slope of m, can be represented by the equation y = mx
+ b.
A line is drawn on the coordinate plane that passes through the point (3,-6) and has a slope of 4. The y-intercept of the line is .

Answer:
b = -18
Step-by-step explanation:
<h3>Slope y-intercept form: y =mx +b</h3>
Slope = m = 4
Plugin the value of slope in the above equation.
y = 4x + b
Now, the line passes through the point (3 , -6). Substitute x and y coordinates in the above equation.
-6 = 4*3 + b
-6 = 12 + b
b = -6 - 12
b = -18

Answer:
b= -18
Step-by-step explanation:
x=3, y= -6, m=4
y=mx+b
-6 = 4 x 3 + b Solve for b
-6 = 12 + b
-6-12 = b
b= -18
