Aline passes through the point (-8,-7) and has a slope of 3. write an equation for the line

Answer

y = 3x + 17

Explanation

If you you want to find the equation of a line you require a point on that line and is gradient.

gradient = 3

a point on the line is (-8, -7)

Chose another general point (x, y)

gradient = (change in y)/(change in x)

3 = (y- -7)/(x- -8)

3 = (y+7)/(x+8)

3(x+8) = y+7

3x+24 = y+7

y = 3x + 24 - 7

y = 3x + 17

step-by-step explanation:

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)
