1. a) Find the y-intercept of the line, then you find the slope the line, and then you can write the equation in y-intercept form, which is y=mx+b, m is the slope and b the y-intercept.
y= x+70 is the equation
b) 70
c) 120
Answer:
2/3
Step-by-step explanation:
Pick two points on the line
(-2,0) (1,2)
Using the slope formula
m = (y2-y1)/(x2-x1)
= ( 2-0)/(1--2)
(2-0)/(1+2)
2/3
Step 2 , supposed to be 4^-15 instead of 4^-2. Always multiply the exponents together.
