Answer is y = 1.4x - 4.8
Step by step
We know coordinates (2, -2) and we know “m” slope is 1.4
Your formula is
y - y1 = m (x - x1)
Substitute your y and x and m values
y - -2 = 1.4(x - 2)
distribute
y + 2 = 1.4x - 2.8
Subtract 2 from both sides to isolate y
y + 2 - 2 = 1.4x - 2.8 -2
Combine and your answer is
y = 1.4x - 4.8
