Answer:
line r: y=-2x-2
line s: -2x+1
lime t: -2x+3
Step-by-step explanation:
every slope must be -2 since that's stated in the question
to find b in y=mx+b, you substitute 0 for x and the y coordinate when x is 0 into the equation (for example for slope r, when x is 0 then y is -2, so -2=-2(0)+b) then solve for b (-2=-2(0)+b is -2=b)
basically, b is the y component when x is 0
Answer: 7
Step-by-step explanation:
3+6^(2) / 9
3 + 36 / 9
3 + 4
7
Answer:
Undefined because the x values are the same
Step-by-step explanation:
Slope: y2 - y1 / x2 - x1
Slope: 7 - 10 / -3 - - 3
Slope: -3 / -3 + 3
Slope: -3 / 0
Slope: undefined
Answer:
x = 45
Step-by-step explanation:
x + 135 = 180 {Linear pair}
x = 180 - 135 {Subtract 135 from both sides}
x = 45
