Question

What is the equation of a line that passes through point R(−4, −3) and has a slope of 7? a. y = 7x + 25 b. y = 7x − 25 c.y = 7x + 3 d. y = −7x − 3

Answer 1

y = mx + b
slope(m) = 7
(-4,-3).....x = -4 and y = -3
now sub into the formula and find b, the y int
-3 = 7(-4) + b
-3 = -28 + b
-3 + 28 = b
25 = b
so ur equation is : y = 7x + 25 <===
