The equation of a straight line is given by: y = 5.2x + 2.6 At what point does it pass through the y-axis? (The options below are given as x,y coordinates)

(5.2, 0)

(0, 5.2)

(0, 2.6)

(2.6, 0)

A straight line on an x-y graph passes through the points (3,2) and (5,6). Derive the equation for this straight line.

y = 0.5x + 0.5

y = 2x - 4

y = 0.5x + 2

y = 2x - 1

The value of h is a linear function of M according to the equation: h = 4.2(M + 2) If h is plotted as a straight line on an x-y graph against M, what would be the slope and intercept of that line.

Slope = 1.0, Intercept = 12.6

Slope = 4.2, Intercept = 2.0

Slope = 4.2, Intercept = 8.4

Slope = 8.4, Intercept = 4.2

A straight line has an equation 3y = 4x -5. At what point does it pass through the x-axis?
