Answer

y = $\frac{3}{2}$x + 3

Work Step by Step

The given x- intercept is -2 and the y- intercept is 3. An equation of a line is y=mx+b where b is the y- intercept. We substitute b=3 y=mx+3 We use the x-intercept of -2 to find the m by substituting x=-2 and y=0 y=mx+3 0=m(-2)+3 We subtract 3 from both sides -3 = -2m We divide 2 from both sides m = $\frac{3}{2}$ The equation of the line is y = $\frac{3}{2}$x + 3
