Alrighty, so:
1.) Slope-intercept form is y=mx+b therefore the answer to question 1.) is y=1.8x+4. Where m=1.8 and b=4
2.)Point-slope form is y-y1=m(x-x1) therefore the answer to quesiton 2.) is y-96=18(x-5). Where m=18, x1=5, and y1=96.
3.) Standard form is Ax+By=C therefore the answer to question 3.) is 4x+y=40. Where A=4, B=1, and C=40.
Hope this helps!
