Ax + By = C
y = 4x + 7
Move the 4x to the other side with a negative sign
-4x + y = 7
We can’t have the coefficient of x be negative, so multiply the whole equation by -1
So, the standard form is 4x - y = -7

Write the equation 2x-5y=20 in slope intercept form

Zigmanuir [339]

Answer:

Step-by-step explanation:

2x-5y=20

Making y the subject

-5y = -2x + 20

Dividing by -5

y = -2/-5x + 20/-5

y = 2/5x - 4

So comparing with y = mx + c

Slope m = 2/5

Intercept c = -4
