Question

Write the equation of a line with a slope of - 5 that passes through (7, 1)

Answer 1

y=mx+36

Explanation:

y=mx+b ==> slope-intercept form equation

1=-5(7)+b ==> plug in known values

1=-35+b

1+35=-35+35+b

b=36

y=mx+36 ==> plug in 36 for b

Answer 2

Answer: y=-5x+36

Explanation:

slope intercept form: y=mx+b

m= slope, which is given as -5

b is y-intercept

y=-5x+b

sub-values from (7,1) into the equation

1=-5(7)+b

1=-35+b

b=36

y=-5x+36
