Step-by-step explanation:
Answer:
-2, 9
Step-by-step explanation:
Well gradient means "slope" I just found out from searching the web.
First let's put y = 4 + 2x into slope intercept form of y = mx + b
y = 2x + 4
"m" is the slope, in this equation it would be 2.
The slope or "gradient" is 2.
The y-intercept of any equation in slope intercept form is the value of "b"
In this equation, the y-intercept is 4.
Distributive property
(7 * 4y) + (7*9) = 28y + 63
