Question

Write an equation of the line that passes through the given point and has the giver slope. (2,4), slipe 2

Answer 1

Slope-intercept form:

y = mx + b

"m" is the slope, "b" is the y-intercept (the y value when x = 0)

Since you know m = 2, you can plug it into the equation

y = mx + b

y = 2x + b

To find "b", plug in the point (2,4) into the equation

y = 2x + b

4 = 2(2) + b

4 = 4 + b    Subtract 4 on both sides

0 = b

y = 2x + 0      

y = 2x
