Answer: y=3x+4
Step-by-step explanation:
slope-interept = y=mx+b, first we need to find the slope. To find the slope, we need to use the formula [tex]m=\frac{y_{2}- y_{1}}{x_{2} -x_{1}}[/tex]
[tex]m=\frac{-8-4}{-4-0} \\\\ m=\frac{-12}{-4} \\\\ m=3[/tex]
To find the y-intercept, You can use either (x,y) point you want because the answer comes out the same for both points.
(0,4). y=mx+b or 4=3 × 0+b, or solving for b: b=4-(3)(0). b=4.
(-4,-8). y=mx+b or -8=3 × -4+b, or solving for b: b=-8-(3)(-4). b=4.
y=3x+4
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)
