Step 1.2.1.1

Raise $5$ to the power of $2$ .

$y = 25 + 8 x - 7$

Step 1.2.1.2

Subtract $7$ from $25$ .

$y = 8 x + 18$

Step 2

Use the slope-intercept form to find the slope and y-intercept.

Step 2.1

Find the values of $m$ and $b$ using the form $y = m x + b$ .

$m = 8$

$b = 18$

Step 2.2

The slope of the line is the value of $m$ , and the y-intercept is the value of $b$ .

Slope: $8$

y-intercept: $(0, 18)$

Slope: $8$

y-intercept: $(0, 18)$
