Step-by-step explanation:
To find the slope, pick any two points fromthe line.
(2,2) & (0,-4)
x₁ = 2 & y₁ = 2
x₂ = 0 & y₂ = - 4
Slope = 3
At y-intercept x = 0.
From the graph, y-intercept = -4
Equation of the line: y = mx + b
y = 3x - 4
Answer:
-3
Step-by-step explanation:
g(1) = -3x² + x - 1
= -3() + 1 -1
= -3(1) + 1 - 1
= -3 +1 -1
g(1) = -3
Just put the 1 everywhere you see an x.
