PLEASE HELP
Amira is told there is a trick to finding the slope within an equation in standard form, Ax+By=C.She is told she can rewrite this equation in slope-intercept form, y=mx+b, to find the pattern. She correctly rewrites the equation 7x+9y=14 in slope-intercept form as y=−79x+149.
Which answer explains the pattern for how to find the slope using an equation in standard form?
A.In slope-intercept form, the slope is −79.These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is −BA.
B.In slope-intercept form, the slope is −79.These values are A and B, but with the opposite sign, so the slope of the line from the equation in standard form is −AB.
C.In slope-intercept form, the slope is 149.. These values are C and A, but with the opposite sign, so the slope of the line from the equation in standard form is −CA.
D.=In slope-intercept form, the slope is 149. These values are C and B, but with the opposite sign, so the slope of the line from the equation in standard form is −CB.
