Question

how do you rewrite y=-3.5+2(x+4.5) in intercept form?

Answer 1

We need to get into the form \[{x \over a} + {y \over b} = 1\]Simplify the given equation to be \[y = 2x + 5.5\]Find the x and y-intercept. Set x = 0 to find y-intercept.\[y = 5.5\]Set y = 0 to find x-intercept. \[x = -2.75\] In the above equation, a is the x-intercept and b is the y-intercept.
