Answer:
The number is -3
Step-by-step explanation:
Write an equation
2x+4=-10
add 4 on both sides
2x=-6
divide 2 on both sides to isolate variable
x=-3
The x-intercept is 3 and the y-intercept is -2
Answer:
-14 and 4
Step-by-step explanation:
add and subtract 9 from -5
Answer:
2
Step-by-step explanation:
cuz
Slope-intercept form is y = mx + b.
In this form, m is slope and b is y-intercept.
Slope is rise over run. The formula for this is (y2-y1)/(x2-x1).
Y-intercept is the value of y when x is equal to 0.
1. Slope = 8 ; Y-intercept = 0
y = mx + b
m = 8 ; b = 0
y = 8x + 0
y = 8x
2. Slope = 1 ; Y-intercept = 2
y = mx + b
m = 1 ; b = 2
y = 1x + 2
y = x + 2
The answer to #1 is y = 8x.
The answer to #2 is y = x + 2.
Hope this helps!
