Answer:
y = x + 2
Step-by-step explanation:
To find the slope:
Find two spots where the line intersects and exact point. (-8,-4)(-4,-1)
Either count up & over or do y1-y2 / x1-x2 (-4+1)/(-8+4) -3/-4 3/4
The intercept is where it crosses the y-axis, in this case 2
Write the equation like this y = mx + b where m=slope & b=intercept
y = 3/4x + 2
