Question

What is the equation of a line that has an x-intercept of 5 and a slope of 4?

Answer 1

y=4x-20

Step-by-step explanation:

Since we already have a slope, all we need to do is just find the y-intercept. To do this we can make an XY t-chart.

Using the chart we can see that for every x that decreases, a y decreases 4 times. So if we subtract 5 from x, we will multiply 5 times y. Note that this graph is increasing so the y-intercept is negative. -5 · 4 = -20

X | Y

6 | 4

5 | 0

0 | -20

Hope this Helps!
