Question

write an equations in slope-intercept form of the line that passes through the point(5,9) with slope 7

Answer 1

Answer:

$y=7x-26$

Step-by-step explanation:

1) Write it in the slope-intercept form of $y=mx+b$, where m is the slope and b is the y-intercept.

$y=7x +c$

2) Substitute the given coordinates into $y=7x +b$, and then solve for c.

$9=7(5) +b\\9=35+b\\9-35=b\\b= -26$

3) Substitute c into $y=7x +b$

$y=7x-26$

Therefore, the answer is $y=7x-26$.
