Question

Write an equation in slope-intercept form for the line that satisfies the following condition. slope 7, and passes through (5, 30)

Answer 1

y = mx + b
slope(m) = 7
(5,30)...x = 5 and y = 30
now we sub and find b, the y int
30 = 7(5) + b
30 = 35 + b
30 - 35 = b
-5 = b

so ur equation is : y = 7x - 5 <==
