Do you know what the pointslope formula is? If so, could you write it out?

use the unknown equation formula. since we have m=4/5 and one point (7,9) x1,y1 yy1=m(xx1) y9=4/5(x7) expand and solve for y to be on the LHS to look like this y=......

pointslope form/general linear equation would be y=mx+c m=gradient c=yintercept.

Just leave whatever you get in point slope formula. You don't have to rearrange it. Which is yy1=m(xx1)

So you would leave y9=4/5(x7) as is, except change x7 to x+7

point slope formula is meant to be y=mx +c so I believe u have to rearrange for y to be on the LHS

y=mx+b is the slope intercept form. yy1=m(xx1) is the point slope form.

u are right, I just briefly searched it, sorry I didn't know the difference.

never knew yy1=m(xx1) was called point slope form, thought it was y=mx+b/y=mx+c

Since the question requested for point slope form, leave it as y9=4/5(x+7)
