The slope is 2
y=2x + b
Plug in a point to solve for b
8 = 2(3) + b
8 = 6 + b
b = 2
The equation is y = 2x + 2
Y -3 =9 solve for y 4w = 24 solve for w y -3 =9 solve for y

Given equation is y=2x+7 and
Let's simplify the 2nd equation before we can start graph so that calculation will be easy
multiply both sides by 2 to cancel out fractions
y=2x+7
which is exactly same as the first equatoin so graph of both will be exactly same and solution will be infinitely many solutions.
y=2x+7 has y-intercept 7 so first point will be (0,7). Slope is 2 so rise 2 unit up then 1 right and graph the new point.
For the X intercept you set y = 0 and solve for x
Y =
x + 9
0=x + 9 subtract 9 from both sides
-9 =
divide both sides by 3
-3 = -8x divide both sides by -8
= x
X-intercept = (, 0)
Y =
0=
-9 =
-3 = -8x divide both sides by -8
X-intercept = (
