Answer:
y = 0.8x + 3
Explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given slope m = 0.8 , then
y = 0.8x + c ← is the partial equation
to find c , substitute the point (5, 7 ) into the partial equation
7 = 0.8(5) + c = 4 + c ( subtract 4 from both sides )
3 = c
y = 0.8x + 3 ← equation of line
