graph the function y=70x+50

Question

Graph the slope intercept function y=70x+50

Answer 1

Find the x and y intercepts, plot them, then draw a straight line that passes through the intercepts.

y-intercept:

b = 70(0) + 50

b = 50

The line crosses the y-axis at (0,50).

x-intercept:

0 = 70x + 50

x = -5/7

The line crosses the x-axis at (-5/7,0).

Plot these 2 points and draw a straight line through them.
