Answer:
Step-by-step explanation:
Slope-intercept form: y = mx + b
Slope formula:
Given points: (-4, 3), (0, 2)
(0, 2) = (x1, y1)
(-4, 3) = (x2, y2)
To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.
First, let's find the slope. To do this, input the given points into the formula used to find slope:
Simplify:
3 - 2 = 1
-4 - 0 = -4
The slope is .
To find the y-intercept, input the slope and one of the given points(in this example I'll use point (0, 2)) into the equation and solve for b:
2 = 0 + b
2 = b
The y-intercept is 2.
Now that we know the slope and the y-intercept, we can write the equation:
Answer:
y = -8
Step-by-step explanation:
To find the value for y, use the slope formula:
Substitute m = 3 and (-9,y) and (-7,-2).
2x−3x=−1x
So −1x=11
1x=x
Divide by −1 on both sides
so the answer is
x=−11
a=-5/2
Step-by-step explanation:
-6a=-5-8a
-6a+8a=-5-8a+8a
2a=-5
a=-5/2
