Answer:


y=\displaystyle (3)/(2)x-(31)/(2)

Explanation:

Hi there!

Slope-intercept form:
y=mx+b where m is the slope and b is the y-intercept (the value of y when the line crosses the y-axis)

Notice how y is isolated in slope-intercept form.


y+5=\displaystyle (3)/(2) (x-7)

To change this into slope-intercept form, isolate y.

Use the distributive property on the parentheses:


y+5=\displaystyle (3)/(2)x-(21)/(2)

Subtract 5 from both sides:


y=\displaystyle (3)/(2)x-(21)/(2)-5\\\\y=\displaystyle (3)/(2)x-(31)/(2)

I hope this helps!
