What is the slope of the line that passes through the points (4, 2)(4,2) and (-16, -10) ?(−16,−10)?

y = 0.6x - 0.4

We have : y = ax+

(2,4)      => 2 = 4a + b          (1)

(-10,-16) => -16 = -10a + b     (2)

(1)(2) => a=0.6 , b= -0.4

=> y = 0.6a - 0.4

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)
