Question

Write the equation that describes the line in slope-intercept form: slope= 4, point (3,-2) is on the line

Answer 1

Slope intercept form is y=mx+b
m=slope
b=y intercept

slope is 4
y=4x+b
subsitute if iin (x,y) form
so x=3 and y=-2 is one solution
subsitute
-2=4 times 3+b
-2=12+b
subtract 12 from both sids
-14=b

the equation is y=4x-14
