Answer: y = -4x + 16
Point-slope form would be (y - 4) = -4(x - 3)
Step-by-step explanation:
To find the y intercept, substitute the y and x values from any given coordinate into the slope intercept form and solve for b
y= mx + b
4 = (-4)(3) + b -4(3)= -12 Add 12 to both sides
4 +12 = -12 +12 + b -12+12=0 Cancel on right
16 = b This is the y-intercept
Rewrite the equation, y= mx + b
Substitute the given slope -4 for m and 16 for b
y = -4x + 16
