Question

A line has a slope of – 2 and passes through the point (11,– 19). Write its equation in slope-intercept form

Answer 1

Answer:

y = -2x + 3

Step-by-step explanatiion:

We can use the point- slope formula to solve.

y - y1 = m(x - x1)

let slope m = -2 and (11, -19) be (x1, y1)

y -(-19) = -2(x - 11)  distribute

y + 19 = -2x + 22

We want slope-intercept form (y = mx + b) so solve for y

y = -2x + 22 - 19

y = -2x + 3
