Question

find the equation with these points (-4,.0016),(-2,.04),(0,1),(1,5),(2,25)

Answer 1

First Find the Slope of 2 points
lets use (0,1),(1,5)

y2-y1/x2-x1 ---->5-1/1-0 =4

so the slope is 4.

now if you look at the point (0,1) you see that 1 is the y intercept because the point (0,1) is on the y axis

you only need the sl0pe and y intercept to find the equation

now use this formula
y=mx+b where m is the slope and b is the y intercept.

plug in 4 for m and 1 for b
and you get the answer


y=4x+1
