1. Write an equation for a line that has a slope of 4 and passes
through the point (-4, 7).

(y - 7) = 4(x + 4) or y = 4x + 23

Step-by-step explanation:

In point- slope form, the equation of a line is (y - y₁) = m(x - x₁)

The slope is given as 4, and so is point (x₁ , y₁). Substitute (-4, 7) as (x₁ , y₁), and do not forget to change the sign to a positive when you get a double negative.

(y - 7) = 4(x + 4) can further be expanded to slope- intercept form as y = 4x + 23

answer is because 4×10=40

and 98×4= is 392
