Slope: rise over run
4 up and 2 to left
4/2 = 2, the slope is 2
I guess its 3.5x (edited) .....
Answer:
C
Step-by-step explanation:
-4/3 x - 6 = -26
Add 6 to both sides
-4/3 x = -20
Divide both sides by -4/3, which is the same as multiplying by reciprocal
-20 * -3/4 = 15
x = 15
Look like a linear equation. let's try finding the slope:
(7-4)/(1-0)=3
(4-1)/[(0-(-1)]=3
[1-(-2)]/[-1-(-2)]=3
indeed, it is linear, with a slope of 3
when x=0, y=4, so the y intercept is 4
the equation of the line is y=3x+4
