Answer:

y = 5x - 2

Explanation:

The equation at the bottom is already in slope-intercept form, or y = mx + b format. It lacks one missing piece: b, or the y-intercept. However, the slope of the equation must be 5, because the number in place of the m equals the slope.

So, use the point-slope formula
y-y_1 = m (x-x_1), and substitute
m,
x_1, and
y_1 for real values. From there, we can isolate y to receive the full equation in slope-intercept form.

Since m represents the slope, substitute 5 in its place. Since the
x_1 and
y_1 represent the x and y values of a point the line intersects, choose any of the points provided and substitute its values into the formula. (Either one is fine, and I chose (1,3).) From there, isolate y to find the slope-intercept form and answer:


y-(3) = 5 (x-(1))\\y - 3 = 5(x-1)\\y - 3 = 5x -5\\y = 5x - 2
