m=7 , (0,7)

Use the formula for the equation of a line to find b.

y=mx+b

Substitute the value of m into the equation.

y=(7)⋅x+b

Substitute the value of x into the equation.

y=(7)⋅(0)+b

Substitute the value of y into the equation.

7=(7)⋅(0)+b

Find the value of b.

Rewrite the equation as (7)⋅(0)+b=7.

(7)⋅(0)+b=7

Simplify (7)⋅(0)+b.

Multiply 7 by 0.

0+b=7

Add 0 and b.

b=7

b=7

b=7

b=7

Now that the values of m (slope) and b (y-intercept) are known, substitute them into y=mx+b to find the equation of the line.

y=7x+7
