Question

Find the equation of a line whose slope is 4 and which passes through the point (3,7)​

Answer 1

Answer: y=4x-5

Explanation:

The formula for a line in slope-intercept form is y=mx+b, where m Is slope and b is y-intercept.

We are given some information that we can use to plug into the formula to complete the missing variables.

`7=4(3)+b` [multiply]

`7=12+b` [subtract both sides by 12]

`b=-5`

Putting the pieces together, we get y=4x-5.
