Answer:
D. y = 4x + 9
Step-by-step explanation:
a line that passes through the point (-2, 1) and has a slope of 4
y = 4x + b
b = y - 4x
b = 1 - 4(-2)
b = 1 + 8
b = 9
So equation
y = 4x + 9
Answer:
Which graph represents the solution set to this system of equations? –x + 2y = 6 and 4x + y = 3
On a coordinate plane, a line goes through (negative 1, negative 1) and (0, 3) and another line goes through (1, 4) and (2, 2).
On a coordinate plane, a line goes through (negative 4, 0) and (0, 4) and another line goes through (negative 1, 1) and (0, negative 3).
Step-by-step explanation:
Answer:
(2, 3)
Step-by-step explanation:
-6x-4y=-24
Divide by -2
3x+2y=12
y=5x-7
Substitute
3x+2(5x-7)=12
3x+10x-14=12
13x=26
x=2
y=5*2-7=3
