Answer:
y = 3x + 4
Step-by-step explanation:
y = mx + c where m is the slope and c is the y intercept.
Slope =
Slope (taken from points (0, 4) and (1, 7)) =
= 3
y-intercept = 4
Equation: y = 3x + 4
Answer:
Step-by-step explanation:
multiply the one to each bracket =
(x +2)+ (x-1) = 3 add the Xs and the numbers
x+X = 2x
2+(-1)= 1
2x+1=3
2x=3-1
2x =2
x =2/2
x =1

Answer:
Step-by-step explanation:
Well it doesn't help you very much, but the answer is A. What this does is separates 7/8 x so that (x/8) sits by itself. After you subtract 3/4 from both sides, you can divide both sides by 7. When you do that, you get x/8 = something, but the fractions are going to be awkward at best. I'll just do a very quick run through
7(x/8) = -6 - 3/4
7(x/8) = - 6.75 Divide by 7
x/8 = 0.9642 Multiply by 8
x = 8 * 0.9642
x = 7.7143
