Answer: y=-3/4x+43/4

Explanation:

y = mx+b

m is the slope, and

b is the y-intercept

m= y2-y1 / x2-x1

m= 10-7/ 1-5

m=-3/4

Answer: y =
-(3)/(4)x + 10
(3)/(4)

Explanation:

If we know the two points, we can find the slope and write a point-slope equation.

Slope


\displaystyle (y_(2) -y_(1) )/(x_(2) -x_(1) )=(10-7)/(1-5) =(3)/(-4) =(-3)/(4)

Point-slope equation

y -
y_1 = m(x -
x_1)

y - 7 =
-(3)/(4)(x - 5)

y - 7 =
-(3)/(4)x + 3
(3)/(4)

y =
-(3)/(4)x + 10
(3)/(4)

Slope-intercept form equation

y =
-(3)/(4)x + 10
(3)/(4)
