Answer:
slope intercept form- y=mx+b
m=slope
b=y-intercept
how to find slope= rise/run
how to fine y-intercept= go straight down the y axis (up and down in the center of the graph) until you come across a point
slope=3
y-intercept=-1
answer= 3x-1
Answer:
Step-by-step explanation:
eq. of line parallel to AB is y=2x+a
if it passes through (3,-2) then
-2=2×3+a
a=-2-6=-8
y=2x-8
Answer:
Step-by-step explanation:
multiply both sides of the equation by 3
Answer:
x = - 9 (negative 9)
Step-by-step explanation:
The x intercept is where y = 0. When y = 0, the point is on the x axis.
So use the equation and replace y with 0.
-2x + 1/2y = 18
-2x + 1/2(0) = 18
-2x + 0 = 18
-2x = 18
x = - 9
Check you answer by putting your answer for x into the equation. See if it does make y = 0
-2x + 1/2y = 18
-2(- 9) + 1/2y = 18
18 + 1/2y = 18
1/2y = 0 so y must also equal 0
