Answer: y = 4x + 13
Step-by-step explanation:
y = 4x + 10
First find the slope m
y = mx + C
y - intercept point y
m - slope
x - intercept point x
C - intercept point
From the equation,
slope m = 4
Using the formula for slope
y - y_1 = m(x - x_1)
Given point ( -2 , 5)
x_1 = -2
y_1 = 5
m = 4
Inserting the values given
y - 5 = 4 ( x -(-2))
y - 5 = 4(x + 2) ( point slope form)
y - 5 = 4x + 8
y = 4x + 8 + 5
y = 4x + 13 ( slope-intercept form)
y = mx + C ( slope - intercept form formulae)
