Question

What would an equation be for a line with a slope of 3 and a y-intercept of 7?

Answer 1

Let us use the slope-intercept form for this, with m as the slope and b as a constant.

y = mx + b

7 = 3(0) + b [since the y-int is 7, the x value will be zero]

b = 7

y = 3x + 7

Answer 2

y = 3x + 7

Explanation:

Using the formula y = mx + b we can create this equation.

m = slope

b = y -intercept

based on the information provided I know that

Slope = 3

and

y-intercept = 7

Substitute:

y = mx + b

y = 3x + 7

y = 3x + 7 is the equation when the slope is 3 and the y intercept is 7.
