Question

A line passes through the point (-10,-7) and has a slope of

2 Write an equation in slope-intercept form for this line.

Answer 1

Answer: Below

Explanation:

so using slope intercept form, we know that y = mx + b. We plug in our values. Since -10 is the x value and -7 is the y value, and 2 is the slope:

-7 = 2(-10) + b

Simplify.

-7 = -20 + b
13 = b

We plug b into the slope intercept form, this time without an x or y value to make it apply to all points on the line.

y = 2x + 13

That's our answer.
